Function Description

The Bosch GSR and GSB Professional machines are designed for driving in and loosening screws, as well as for drilling in wood, metal, ceramics, and plastic. The GSB models offer additional functionality for impact drilling in bricks, brickwork, and masonry. These are battery-operated tools, emphasizing portability and cordless operation. The tools feature a rotational direction switch, a gear switch for speed selection, and an operating mode selector switch for different applications.

Important Technical Specifications

The technical data for these machines are detailed in the manual, typically on pages 205-206. Key specifications include:

Voltage: 14.4 V-LI and 18 V-LI, indicating the battery voltage.
No-load Speed: Separate values for 1st and 2nd gear (n₀ 1 and n₀ 2), allowing for precise speed control depending on the task.
Maximum Torque: According to ISO 5393 (M), crucial for screwdriving applications.
Drilling Diameter: Maximum drilling diameters for metal (Ø) and wood (Ø), and for brickwork (Ø) in GSB models, indicating the tool's capacity for different materials.
Chuck Clamping Range: (E) specifies the range of drill bit and screwdriver bit sizes the chuck can accommodate.
Impact Rate: (ns) for GSB models, indicating the number of impacts per minute during impact drilling.
Weight: According to EPTA-Procedure 01/2003, providing an indication of the tool's portability.
Noise/Vibration Information: Includes sound power level (LWA), sound pressure level (LPA), and vibrational emission value (ah), measured according to EN 60745. Uncertainty (K) values are also provided. These values are important for assessing potential health risks and ensuring compliance with safety regulations.
Battery: Equipped with NTC temperature control, allowing charging only within a temperature range of 0 °C and 45 °C to ensure a long battery service life.

Usage Features

The manual outlines several usage features and safety guidelines:

Cordless Operation: Emphasizes the convenience and flexibility of battery-operated tools.
Adjustable Torque: The ability to set the torque (Figure 5) prevents over-tightening of screws and damage to the workpiece or screw head.
Multiple Operating Modes: The operating mode selector switch (Figure 7) allows users to switch between screwdriving, drilling, and impact drilling (for GSB models), making the tool versatile for various tasks.
Gear Selection: Mechanical gear selection (Figure 8) provides different speed ranges, with low speed (1st gear) for high torque applications like driving large screws, and high speed (2nd gear) for drilling.
Rotational Direction: A switch (Figure 4) allows for easy reversal of the rotational direction, essential for both driving and loosening screws.
Quick Accessory Change: Instructions for mounting application tools (Figure 3) and selecting accessories (page 211) highlight the ease of switching between different bits and drills.
Ergonomic Design: The grey-marked area on the handle indicates an insulated gripping surface, enhancing user comfort and safety.
Battery Management: Instructions for removing (Figure 1) and inserting (Figure 2) the battery, along with advice to fully charge the battery before first use to ensure full capacity. The NTC temperature control helps maintain battery health.
Workpiece Security: Recommends securing the workpiece with clamping devices or a vice for safer operation.
Dust Extraction: Mentions provisions for connecting dust extraction and collection facilities, which helps reduce dust-related hazards.

Maintenance Features

Proper maintenance is crucial for the longevity and safe operation of the tool:

Cleaning: Emphasizes keeping the machine and ventilation slots clean for safe and proper working.
Tool Inspection: Users are instructed to check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool's operation. Damaged tools must be repaired before use.
Cutting Tool Care: Advises keeping cutting tools sharp and clean to prevent binding and ensure easier control.
Battery Care: Instructions to protect the battery against heat, fire, water, and moisture. Also, to only recharge with the specified charger and use only original Bosch battery packs to prevent risks of injury and fire.
Professional Service: Recommends having the power tool serviced by a qualified repair person using only identical replacement parts to maintain safety.
Storage: Advises storing idle power tools out of the reach of children and setting the rotational direction switch to the centre position during transport and storage to prevent unintentional starting.
Hazardous Materials: Provides warnings regarding dusts from materials like lead-containing coatings, wood, minerals, and metal, emphasizing the need for good ventilation and protective equipment like P2 filter-class respirators. Asbestos-containing materials should only be worked by specialists.
